BOBBIN-STRIPPER.

Specification of Letters Patent.

Application filed March 11, 1916. Serial N0. 83,472.

To all whom 'it ymay concern:

Be it known that I, JouN Cnam, a citizen ofthe United States, and a resident of New York Mills, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Bobbin- Strippers, of which the following is a speellication.

This invention relates to improvements 1n devices for removing yarn froln bobbins of the type used in connection with loom shuttles for supplying filling in the weaving of textile fabrics.

rThe principal object of the invention is to provide means for automatically engaging the loose end of the unwound yarn an stripping the same for the bobbins.

Another object is to provide means whereby the yarn may be easily and rapidly removed from the stripping device. and finally to feed the bobbins against, past and away from the stripper automatically, the time consumed by the. passage of each bobbin being dependent upon the amount of yarn upon it.

These and other related objects are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawings forming a material part of this disclosure and in which Figure 1 is a partial end and sectional view of an embodiment of the invention, showing the driving and .bobbin feeding means, the section being taken on line 1 1 of Fig. 2. Fig. 2 is a front view of the same, certain parts being broken in order to show the interior. Fig. 3 is an enlarged side view of the stripper cone. parts being broken away that the construction may be better seen. Fig. 4 is a view looking at the smaller end of the stripper cone. Fig. 5 is a cross sectional view, taken on line 5-5 of Fig: 3. Fig. 6 is another view taken on the same line but showing the parts in another position. Fig. 7 is a side view of the container in which the filled bobbins are operated upon. Fig. 8 is a similar view of the container for receiving the bobbins after being stripped of the yarn. Fig. 9 is an end view of the container shown in Fig. 7. Fig. 10 is a cross sectional View, taken on line 10-10 of F ig. 7, and Fig. 11 is a partial end view of the container, shown in Fig. 8.

The main feature of the invention consists in a collapsible stripper mounted at one end in a rigid support 15 having an elongated hub 16 through which passes a revoluble shaft 17, provided at its outer end with a sprocket wheel 18. the hub of which is secured to the shaft. i

At the inner side of the support 15, coiled about the shaft is a helical spring 21, the same being connected at one end to the collar 22 fixed to the shaft, which is caused to rotate by the chain 25, driven by the sprocket wheel 26 on the sha-ft 27, the chain engaging direct with the sprocket 18. Looselv mounted on the shaft 17, near the collar` 22, is a circular disk 30. caused to rotate by the other end of the spring 21 and held bv a collaighaving the set screw G5, the point of which engages in an annular groove formed in the shaft; a similar but smaller disk 3l. being at the outer end of the shaft; extending between these disks are two oppositely disposed plates 32, curved to suit the disks and forming the tapering walls of a cone, having between their adjacent edges open spaces 33. Passing through an opening in the disk 31 and extending to the larger fixed disk is a tubular sleeve 35, projecting outwardly beyond the shaft at its unsupported end and having a handle bar 36 set therein by which it may be turned relative to the shaft 17.

Formed with the sleeve are opposit'ely disposed lugs 38 and 39, near the larger and smaller ends respectively of the cone, and to these lugs are pivoted links Ll0 and 4l, the outer ends of which are similarly engaged with inwardly projecting brackets l2 and 4.3, attached to plates 45, positioned, when the links are oppositely extended radially in the spaces 33 of the cone. The

brackets 42 and 43 have formed with them arms 47, curved to suit the interior or .concave side of the cone casing plates 32 and attached respectively to the disks 30 and 31 by the pivot screws 19, so that the plates 45 can be turned in below the normal surface of Jthe cone, together with the fine wire brush strips 50, with which they are faced, the material used being known as card-clothing, of the variety called filleting; thus the contacting elements can instantly be collapsed or drawn within the cone by operating the handle bar 36, as can be seen best in Figs. 5 and 6.

Secured to the support 15, above and central of the axis of the cone, is a rectangular container 55 having an open top 5G, in which the bobbins are placed, the same resting on the inclined surface of the shelf 57 until they are fed by gravity over its edge, dropping upon the reversely inclined. plate 58 where they are partially intercepted by the partition 59, made preferably of textile fabric and adapted to engage With and draw out the loose end of the yarn upon the bobbins as they pass to the stripper cone. The lower container GO receives the bobbins when stripped and when filled can be readily removed and emptied of its contents; a plate 6l partially intercepts the passage of the bobbins so as to break their fall in passing down. lVhen the cone has received such a quantity of yarn as to prevent the wire brushes from engaging with the loose ends of the yarn readily, the brushes are retracted within the shell and the yarn that has been wound upon its surface easily slipped off its smaller end.

From the foregoing it will be seen that' a practical and efficient device is presented adapted to automatically strip the yarn from bobbins without injury to the same, and from which the yarn can be readily recovered.

Having thus described my invention, its construction and operation, what I claim as new and desire to secure by Letters Patent, 1s:-

1. In a bobbin stripper, a hopper in which the bobbins are placed, a flexible textile retarding partition in said hopper, adapted to unravel the loose ends of yarn on the bobbin, a conical stripper upon which the bobbins make contact, and a removable container suited to receive the bobbins after passage past said stripper.

2. In a bobbin stripper, the combination with a hopper, a retarding means adapted to engage with and unravel the loose end of a yarn on the bobbins, a conical stripper revoluble in said hopper, against which the bobbins are brought singly into contact, means for driving said stripper, and a receptacle for receiving the bobbins, said receptacle having a detlecting plate in its upper portion.

3. In a bobbin stripper, a conical hollow roller, wire brushes operable through' openings in the walls of said roll, means for extending or retracting said brushes, and means for feeding bobbins past the periphery of said conical stripper.

1. In a bobbin stripper, the combination with a casing, a conical stripper roll revolubly mounted therein, means for driving said roll, wire brush elements mounted in said roll at opposite points therein, means for projecting said brushes outwardly or retracting the same within said conical roll, and means for stripping said conical roll.

5. In a bobbin stripper, the combination with a casing, a shaft revolubly mounted therein, a disk head fixed upon said shaft,

a sleeve rotated upon said shaft, a second l disk loosely mounted upon said sleeve, curved plates connecting between said disks, having openings between their adjacent edges, brush elements supported by said sleeve, and means combined with said sleeve for projecting or retracting said brush elements with respect to the periphery of the casing plates.

6. In a bobbin stripper, the combination with a hopper, of a flexible retarding means disposed longitudinally therein adapted to engage with and unravel loose ends of yarn on the bobbins, an expansible conical stripper roll revoluble in said hopper, means for feeding bobbins past the periphery of said stripper, and means for removing the gatherings from said stripper roll at desired intervals.
